A synthetic peptide substrate for initiation factor-2 kinases

Biochemical and Biophysical Research Communications, 1991
A peptide P(45-56) corresponding to residues 45-56 (sequence: ILLSELSRRRIR) of eIF-2 alpha was synthesised. It was phosphorylated by both of the well characterised eIF-2 alpha kinases viz.; the heme-controlled repressor (HCR) and the double stranded RNA-dependent inhibitor (dsI).

Antimicrobial Peptide Buforin I Inhibits Tissue Factor-Initiated Coagulation

Archives of Biochemistry and Biophysics, 2001
The enhanced extrinsic blood coagulation following septic shock often manifests cardiovascular complications. The upregulated monocytic tissue factor (mTF) was shown to be a primary contributor to the extrinsic hypercoagulation following acute bacterial endotoxin (LPS) infection. A single-stage clotting assay monitors TF-initiated coagulation.

Protein synthesis in rabbit reticulocytes: Characteristics of peptide chain initiation factors

Biochemical and Biophysical Research Communications, 1972
Summary In a cell-free amino acid incorporating system using preincubated reticulocyte ribosomes, the transfer of methionine from [35S] Met-tRNAfMet in response to poly r((U-G) messenger (in the presence of unlabeled valine, cysteine and crude tRNA) was dependent on addition of the 0.5M KCl wash of crude reticulocyte ribosomes.

TNF alpha and cortisone impair peptide chain initiation by altering the availability of initiation factor EIF-4E

Frontiers in Bioscience, 2003
The effect of chronic tumor necrosis factor-a (TNF-a) and cortisone treatment on the concentration of translational initiation factor eIF-4E in rat skeletal muscle was evaluated. Crude muscle extracts from control and experimental groups (TNF-a s.c. @ 50 microg/kg body wt each day for 5 days or cortisone s.c.

Guanosine triphosphate - dependent autocatalytic phosphorylation of peptide initiation factor 2 from rat liver

Biochemical and Biophysical Research Communications, 1982
If incubated with [γ-32P]guanosine triphosphate, homogenous peptide initiation factor 2 from rat liver liberates the terminal phosphate from GTP and utilizes 25–40% of it for its own phosphorylation. This phosphorylation is apparently autocatalytic since it does not require any additional proteins.

Recognition of eukaryotic initiator tRNA by an initiation factor and the transfer of the methionine moiety into peptide linkage

Biochimica et Biophysica Acta (BBA) - Nucleic Acids and Protein Synthesis, 1972
Abstract A protein factor, obtained from 0.5 M KCl extracts of rabbit reticulocyte ribosomes, forms a GTP-dependent complex with the initiator tRNA from rabbit liver, Met-tRNAMetf. This activity has been purified approx. 125-fold by ion-exchange chromatography upon DEAE-cellulose and hydroxylapatite.
